STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Hi there, I am working on a project using the STM32H755 zi that has 1 USBC port, can we use the same port for uploading the code, UART Communication and powering the device instead of using ST-LINK? Or is there any way to use ST-LINK for communicatio...
Hello, I'm using the STM32F469NiH6 to try and do a certain number of SPI transactions (let's say 12 bytes) at regular intervals without core intervention, using Timers and DMA. And I have a couple of questions concerning this (I have had a look into ...
I set up EXTI so I get interupt on the correct pin GPIO B.6. But I cannot get it to wake up from stop1 mode. I call WFI and RTC wakes upp the processor regularly but EXTI will not. Reading the reference manuel it says any interupt should wake the pro...
I already installed the latest stm32cubeIDE(version 1.15.0).when I was trying to create a new stm32 project, the error present as below:So I want to install install software package first, but the help->manage embedded software package is no response...
Hi,Master:Question：When the finished product cannot be debugged with jlink, I want to save and trace the function stack information through the firmware. When there are some accidental exceptions, I need to use the function stack to more delicately l...
Hello all,I am attempting to read the direction bit and have observed a surprising behaviour. Let’s say my encoder was set to the reverse direction. If I attempt to move the encoder in the opposite direction, the direction bit doesn’t update until I ...
I could cry... ("rrrr", the more I dive into latest STM MCUs - the more I get frustrated - LOL)The datasheet for STM32U5A5, LQFP64 package, tells me: there are PB15 as SAI2_SD_A and also PC12 as SAI2_SD_B.But the CubeMX does not let me configure thes...
Hi ST,i have an inverter project designed with stm32g474xx and there is a "h-bridge" topology in the system.Can I create a uni-polar PWM to get three-level output while controlling this topology with hrtim1?Can hrtim1 create uni-polar pwm outputs (18...
I have a board using STM32F103CBT6 chip. After flashing the board once (through CubeIDE v1.14.0 with ST-Link v2) I cannot flash it again and keep getting the message "No target found". Here's a snapshot of the chip circuit: When I power up the boa...
